TerraMaster D4 SSD: The lightning-fast storage for creative professionals!
The world of storage solutions is getting a little more exciting again because TerraMaster has introduced its latest product, the compact 4-bay storage enclosure for M.2 SSDs, the D4 SSD. This handy gadget is not only a feast for the eyes, but is specifically aimed at creative professionals and video producers who are looking for efficient data storage. With availability starting June 27th, you can soon make your dream of fast and reliable storage come true.
What makes this part so special? Well, the housing uses the innovative USB 4 protocol, which offers impressive data transfer rates of up to 40 Gbit/s - so no data packet is left behind. At a price of 320 euros, the D4 SSD offers the opportunity to use this speed with up to four Samsung 990 PRO SSDs, with read speeds of up to 3,257 MB/s and write speeds of 3,192 MB/s. These values were measured in a RAID 0 array on a Mac mini with an M4 chip under macOS 15.3.2.
Flexible and future-proof
The D4 SSD is not only a fast storage medium, but also extremely flexible in use. It supports M.2 SSDs with up to 8TB per bay, giving a theoretical total capacity of 32TB. This makes them particularly interesting for anyone who needs a lot of storage space. A RAID system can also be implemented for users who are not afraid to invest some time in the software tools.
Another plus is the good compatibility with Thunderbolt 3/4/5 and USB 3.0. However, Windows PC users should be careful: There are occasional detection problems with Thunderbolt 3, although using a different USB port is recommended. Better safe than sorry, they say, in this country we should be prepared for anything.
Data backup made easy
Data backup is also not neglected. There is the TPC Backupper software for Windows and the TDAS mobile app for iOS (from version 15.6) and Android (from version 11). This shows that TerraMaster has a knack for meeting the needs of modern users and can be trusted to capture important moments. Innovative companies like OWC, which also pay particular attention to reliable data storage products, rely on complete development efficiency and test their products under extreme conditions. Therefore, it is not surprising that such storage solutions are consistently recommended.
Choosing the right SSD can be crucial for many users these days. In a year, the market will be dominated by new high-speed SSDs, such as the PCIe 5.0 models, which offer speeds of up to 14.5 GB/s. But the proven PCIe 4.0 SSDs, such as the Samsung 990 Pro, are still the best choice for many users. A look at the best SSDs shows the wide range of possibilities, from gaming to use in NAS systems.

| WD Black SN850X | – | – |
Last but not least, the storage solutions are prepared for the future and help ensure that users now have a large selection of high-quality products. Whether for your next creative project or for everyday use, the new products on the market are worth real consideration.
